Subject: [RFC 3/9] MCE: Always retrieve mce rip before calling no_way_out
Date: Mon, 23 May 2011 15:13:17 -0700	[thread overview]
Message-ID: <4ddadbfd171625de3c@agluck-desktop.sc.intel.com> (raw)
In-Reply-To: <4ddad79317108eb33d@agluck-desktop.sc.intel.com>

From: Andi Kleen <andi@firstfloor.org>

Some of the rules in the decision engine need a valid rip,
so set it up before calling it.
